HUMIDIFIER.

Specication of Letters Patent.

Patented J une 3, 1919.

Application tiled May 11, i918. Serial No. 233,908.

To aZ-Z whom t may concern:

Be it known that we, WILLIAM Gr. SIVIITH4 and JOSEPH P. LISK, citizens of the United States, and residents, respectively, of Scarsdale, in the county of Westchester and State of New York, and of the borough of Brooklyn, in the city and State of New York, have invented a new and useful Improvement in Humidifiers, of which the following is a specication.

The object of our invention is to provide a humidifier which can be readily attached to the supply line of a heating medium such, for instance, as a steam supply line, and which is particularly1 well adapted for attachment between a steam or hot water radiator and its inlet valve.

A further object is to provide a device of the above character which will evaporate a large quantity of water rapidly thus having a maximum efficiency for the purpose intended.

A practical embodiment of our invention is represented in the accompanying drawings, in which-H Figure l represents the humidifier applied to the supply line of a steam heating equipment between the radiator and inlet valve,

Fig. 2 is a top plan View of the humidifier,

Fig. 3 is a section taken in the plane of the line III-III of Fig. 2,

Fig. 4 is a section taken in the plane of the line IV-IV of Fig. 2, and

Fig. 5 is a section taken in the plane of the line V-V of Fig. 3.

The humidier comprises, generally, the heating chamber l and the water evaporating chamber 2, which surrounds the heating chamber. The heating chamber is provided with an inlet 3 for the heating medium and may be provided with one or more outlet ports 4 for the heating medium, it being understood that the outlet or outlets not beingrused may be suitably plugged.

The water evaporating chamber 2 may be provided with a water inlet port 5, through which water may be supplied to the said evaporating chamber. The top of the chamber ifs open to external atmosphere as shown at 6.

The humidifier may be provided with lugs 7 for -attachment to any suitable support or the humidifier may be supported from the supply line 8 of the heating medium by means of a L coupling 9 and a reducing coup-ling 10.

It is to be understood that the humidifier may be attached to any point in the heating system, such as the radiator branch, the main pipe line, the riser, etc. It will also be understood that the water evaporating chamber may be connected to any automatic water supply and humidity controlling den vice so that the water evaporating chamber may be kept automatically supplied with the required amount of water.

t is also to be understood that the humidifier may be applied to various heating systems.

It is evident that various changes may be mode'in the construction, form and arrangement of the several parts of the humidi er without departing from the spirit and scope of our invention; hence we do not wish to limit ourselves to the particular structure herein shown and described, but

What we claim is A humidifier comprising a vertically arranged water evaporating chamber having a water inlet port and an open top, and a heating chamber projecting upwardly into the evaporating chamber and surrounded thereby, said heating chamber having a vertically arranged inlet at its bottom and a laterally arranged outlet port at its top leading through the evaporatng chamber.

In testimony that we claim the foregoing as our invention we have signed our names this fourth day of May, 1918.
